I decided that I would try out 2.5.44, and I noticed that htree was merged. If I don't do the tune2fs -O dir_index, and e2fsck -D, the (exisintg) fs won't use htree, right? Once I do the tune2fs and e2fsck, will I still be able to go back to a non-htree kernel if needed? (Will a htree-ized fs work on a non-htree kernel?) I'm guessing that it won...

Apologies for the newbie question: I have a (stock) 2.4.20 build (*not* -ac), and I'm trying to work with large ext3 directories. By large, I mean 160,000 files per directory. (Yes, I know it would be better in nested directories but such is life). I feel htree would benefit me. Having upgraded from an earlier version of 2.4, I don't see any change, and close reading of the 2.4 changelog suggests that htree isn't in there - only a patch to prevent non-htree builds reporting corruption after being written to by an htree build. Did I read this right...

Guys, I have recently applied the latest 2.4 htree patch on a heavily loaded nfs server. The nfs server serves around four very busy clients that deliver email in maildir format and pop3/imap clients. Being maildir I presumed that the htree patch would improve performance - but I was wrong. Load on the server went up by around 25-40%. After 3-4...

Well here is what I got from testing htree with NFS. http://labs.zianet.com/benchmarks_html/postmark_benchmarks_NFS_100_htree.html It looks like htree improves performance when the storage device is local(as per my previous post) but it looks like htree degrades performance when used in conjunction with NFS. I am going to try it with g...

I've backported all of the bugfixes to the 2.5 dxdir/htree patches to 2.4, and have created a new set of patches for Linux 2.4.21rc5. At this point it *looks* like we've fixed all of the htree bugs that people have reported, including the brelse bug, the memory leak bugs, and the NFS compatibility problems. I've done *very* light testing, and thi...

Hello, Could someone create some newer htree patches for the 2.4.x kernel? There are some bug fixes in the 2.4.21-rc releases that would be nice to have but the htree patches preceed those and they won't apply cleanly to later pre/rc kernels. It sounds like Marcelo may be about ready to put out 2.4.21 so it may just be worth holding off...

...: 1764, N/A, 1078 Remove : 611, N/A, 1310 Ok so results are not that great - better to use more directories. Files spread over 1000 directories: Create: 409, 305, 284 Remove: 138, 96, 141 Create: 377, 312, 276 Overwrite: 317, 246, 268 Overwrite2: 321, 241, 265 I was interested in seeing if the htree patches would give me a performance increase - although I guess the sequential nature of the file creation/deletion probably will not benefit - although I was suprised that adding dir_index hit the overwrite and removal speed - probably based on this testing I won't use this feature (yet). Cpu...

Hi, I'm working with Prof. Zadok on versionfs, a stackable versioning file system. I face some problems with the unlink operation on ext3 with htree. On an unlink, I make a copy of the file (version/backup) and unlink the original file. But some files that have been unlinked are "linked back" to another file. For example, on deleting the file 'foo', the file itself is deleted and its backup is made, but "foo" point...

There's a new set of ext2/3 patches for 2.4.21-pre5 available at: http://thunk.org/tytso/linux/extfs-2.4-update/extfs-update-2.4.21pre5-2 and in broken out form at: http://thunk.org/tytso/linux/extfs-2.4-update/broken-out-2.4.21pre5-2 New to this patch set include: * A kludge to help htree work well with Linux's NFS implementation * Allow the orlov allocator to be disabled via a mount option. * Improvements to the inode and block allocators by Andrew Morton * The bugfix for noatime on newly created inodes * An open by inode number extension (this was an old patch I developed a...

-----BEGIN PGP SIGNED MESSAGE----- Hash: SHA1 Hi, Searching in the ext3 filesystem mailing list I have seen that there is an indexed directory extension for it. Is this extension stable code ? Has anyone test it ? How may I obtain and install it ? Is it available in any of the last kernel releases ? Greetings. - --- Carles Xavier Munyoz Baldó carles@descom.es Descom Consulting Telf: +34

Hi Guys, I am planning on upgrading an existing NFS exported filesystem to the ext3 htree patch on kernel v2.4.23. Will the patch index directories automatically after tune2fs -O dir_index or should I do an e2fsck -Dfy on the filesystem before remounting?

My reading of the kernel.src.rpm doesn't indicate that Severn has ext3 htree patches. Stephen, were there any issues seen during Cerberus testing ? Regards, Yusuf -- Yusuf Goolamabbas yusufg@outblaze.com

Hi Guys, I am quite keen to try out the new htree extensions to ext3 however I wish to use them under NFS. I have noticed comments from the developers saying that it doesn't work properly under NFS. What exactly is the current status of the issue?

...also noticed these in the kernel logs: EXT3-fs warning (device hda12): ext3_unlink: Deleting nonexistent file (612870), 0 EXT3-fs warning (device hda12): ext3_unlink: Deleting nonexistent file (22203), 0 I have never seen this before with exim and ext3. This is the first time I have tried running htree on the exim spool however.
